"Like August before it, September 2014 was the warmest September on record, according to newly updated NASA data. The warm month makes it even more likely that 2014 will become the warmest year on record.

This September was about 1.4°F above the 1951-1980 average temperature for the month, data from NASA’s Goddard Institute for Space Studies (GISS) showed. That makes it the warmest September in GISS records, edging out the previous September record set in 2005. GISS records extend back to 1880.

September followed what both NASA and the National Climatic Data Center (NCDC) rated as the warmest August on record, and what NASA ranked as the fourth warmest summer on record globally. NCDC’s temperature data for September will be released later this week."
